The interrupting ratings climb to 121 kA at 240 V AC and 75.6 kA at 415 V AC, so it clears high-fault conditions upstream of branch panels or motor control centers.
Thermal derating and ambient range
Above that it derates linearly: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at the 70 °C operating maximum. If your panel runs hot near a drive or transformer, size the branch load for the derated figure at the actual ambient.
The 3VA1050-4ED32-0AD0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 76.2 mm width (3-inch footprint) is standard for 3-pole 50 A MCCBs in the SENTRON range — it fits the same mounting slots as the 3VA1010-2ED32-0JA0 without rewiring or bus-bar repositioning. The IP40 front means the breaker face can be exposed in a dead-front panel; no additional cover is needed for the operator handle.
